DIAGNOSIS <TC-SST>

INTRODUCTION

M1225024900011

The TC-SST system can exhibit any of the following
symptoms: noise or vibration is generated or fluid
leaks.

The causes of these symptoms could come from:
incorrect mounting, the fluid level may be low, or a
component of the TC-SST may be faulty.

TROUBLESHOOTING STRATEGY

M1225007900018

Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will find most TC-SST
malfunctions.
1. Gather as much information as possible about the

complaint from the customer.

2. Verify that the condition described by the

customer exists.

3. Check the vehicle for any TC-SST Diagnostic

Trouble Codes (DTCs).

4. If you cannot verify the condition and there are no

DTCs, the malfunction is intermittent. For
information on how to cope with intermittent
malfunctions, refer to GROUP 00, How to Use
Troubleshooting/Inspection Service Points

− How

to Cope with Intermittent Malfunction

P.00-15

5. If you can verify the condition but there are no

DTCs, or the system cannot communicate with
scan tool, refer to the Symptom Chart

P.22C-15

6. If there is a DTC, record the number of the code,

then erase the code from memory using scan tool.

7. Reconfirm the symptom.
8. If a DTC is set again, go to the Inspection Chart

for Diagnostic Trouble Codes.

9. If a DTC is not set again, the malfunction is

intermittent. For information on how to cope with
intermittent malfunctions, refer to GROUP 00,
How to Use Troubleshooting/Inspection Service
Points

− How to Cope with Intermittent

Malfunction

P.00-15

10.Verify malfunction is eliminated. After repairs are

completed, the complaint conditions to confirm
the malfunction has been eliminated.

PRECAUTIONS FOR DIAGNOSIS

With the TC-SST assembly, the IG shutoff delay sys-
tem is adopted to improve the engine starting perfor-
mance.

When the ignition switch is turned OFF, the IG shut-
off delay system release the gear engagement in
preparation for the next engine starting. This is a sys-
tem to delay the engine stop for approximately 1 sec-
ond, and the delay is not a malfunction.

mation display.
If the figure (A) remains displayed on the information screen of
multi information display, check whether or not a diagnostic
trouble code is set.
NOTE: When the figure (B) is displayed on the information
screen of multi information display, the transmission oil temper-
ature is high.
